The IUTAM Symposium on Laminar-Turbulent Transition 2019

Date: 2-6 September 2019

Location: Imperial College London, UK

Scientific scope:  We have received unprecedented interest in the IUTAM Transition 2019. We received nearly 200 abstract submissions. We run
plenary sessions, individual talks and networking sessions. The scientific programme covered a range of fundamental topic areas, including:

• Global analysis of instabilities and receptivities for complex configurations;
• Nonlinear dynamical-systems approaches to minimal seeds and transition to turbulence;
• Influence of multi-physics phenomena on transition: reactive flows, non-Newtonian material behaviour, interfacial flows, flows with interacting structures;
• Novel experimental measurement and evaluation techniques for transition in complex flows;
• Roughness-induced transition; transition from steps, gaps, junctions and other geometric imperfections;
• Transition in hypersonic flows; prediction of thermal loads.
• Active and passive control of flows undergoing transition; transition delay;
• Transition mechanisms in natural and controlled environments; receptivity techniques and studies;
• Late stages of transition and the breakdown to fully developed turbulence;
• Transient growth problems and bypass mechanisms and their role in the transition process.

Outcomes:

• We received very positive feedback from attendees on the well organised and attended meeting.
• Symposium was well attended by early-career academics, post-graduate students, industry representatives, senior members of the community and invited guests.
• 175 registered delegates of which 40% are PhDs
• Evening reception (Monday, 2^nd September) and conferenced dinner (on the 5^th September) provided networking opportunities for attendees to discuss future collaborations.
• The conference proceedings will be published by Springer.
